Stephen Colbert has been ensuring that he isn't rusty when he assumes the Late Show throne in September.

But who knew that he would pop up in Monroe, Mich., on public access cable television to interview a "local Michigander"? Certainly not the folks who usually tune into local talk show Only in Monroe!

None other than Detroit's favorite son Eminem sat down with Colbert today for an interview that could easily have been mistaken for a Between Two Ferns-style spoof (and not only because of that potted plant adding such a domestic, homespun touch to the set).

But no, this was about as real as such a tongue-in-cheek interview could get, and we can only imagine the surge in viewership that Only in Monroe will enjoy.
